Hi,I just discover the vnodes new feature described here:†http://www.datastax.com/dev/blog/virtual-nodes-in-cassandra-1-2In the post above, Brandon says "If youíd like to upgrade an installation to virtual nodes, thatís possible too, but Iíll save that for a later post". Does this post now exist somewhere ?From the cassandra.yaml:# If you already have a cluster with 1 token per node, and wish to migrate to# multiple tokens per node, see http://wiki.apache.org/cassandra/Operations# num_tokens: 256I see no reference to vnodes or num_tokens on this wiki.So, how to switch from "physical" nodes to vnodes ?This is useful only if your number of nodes is greater than the RF, right ?Why 256 token by default ? Where this value come from ?Is there more advantage / disadvantage of using vnodes that improving the internodes data streaming by increasing the number of data sources ?Alain----------------------------------††≠≠††
